Tension self-adjusting feeding roller of stenter setting machine

Abstract

The invention provides a tension self-adjusting cloth feed roll of a tenter. The tension self-adjusting cloth feed roll comprises a threaded roll with convex threads which symmetrically and spirally spread from the middle part to both ends; drive rods are symmetrically arranged at the two ends of the threaded roll; the drive rods penetrate through rolling bearings which are mounted and fixed on floor supporting rods; the bottom ends of the floor supporting rods are blocked to slide rails fixed on the floor; positioning plates vertically fixed on the floor are arranged at the two ends of the slide rails, respectively; elastic pipes are correspondingly arranged on the front and back of the floor supporting rods; the other ends of the elastic pipes are propped against the positioning plates; two or more than two groups of elastic pipes are arranged in the longitudinal direction; a hard hollow pipe penetrates through the outer surface of each elastic pipe, and baffle plates are arranged at the left and right sides of the elastic pipe. The tension self-adjusting cloth feed roll of the tenter is compact in structure, enables a plurality of types of fabrics to be applied to the same cloth feed roll, and therefore, excellent setting effect is achieved.

Description

technical field [0001] The invention relates to a tension self-adjusting cloth feed roller of a stenter setting machine, which can automatically adjust the tension of the cloth feed within a certain range, and belongs to the field of fabric printing and dyeing equipment. Background technique [0002] Stenter setting machine is an indispensable and main equipment in the field of fabric printing and dyeing, and it is a necessary equipment for fabric finishing to improve fabric mechanical properties. During the process of scouring, bleaching, printing and dyeing, due to the radial tension of many machines, the fabric will elongate in the radial direction and shrink in the weft direction, resulting in phenomena such as uneven width, uneven selvedge, and skewed weft yarns. In order to overcome the above shortcomings, the fabric must be tenter finished. Stenter finishing is based on the plasticity of cotton fibers in a wet state. During the drying process, the state of the warp a...

Problems solved by technology

[0003] The fabric enters the drying equipment through the cloth feeding frame, and the cloth feeding roller is installed on the cloth feeding frame. The traditional cloth feeding roller is fixed and fixed. When the fabric enters the drying equipment, after the fabric is dried and stretched, it will tighten radially. Tension, depending on the type of fabric, the drying coefficient in the drying equipment is different, the tension change curve of the fabric is different, and the tension on the cloth feeding roller is also different. When the tension is too large, it is not conducive to the tentering of the fabric. Pull the fabric into an unstable set state
